Asteroids, Cathode Rays & Requisite Knowledge, II

November 18, 2009

Yesterday we talked about asteroids, and the fact that “there’s no evidence for X” type claims are often made amidst the very evidence being denied. We also discussed the interesting truth that an unjustified claim is not necessarily untrue. Today, let’s continue with another example from science’s history to discuss what counts for evidence, when our beliefs are justified, and the extent to which we can lean on either as an epistemological security blanket. Let’s discuss cathode rays!

Asteroids, Cathode Rays & Requisite Knowledge: More Thoughts On Evidence

November 17, 2009

I’ve written recently on evidence here, here and here, and one can always visit TWIM’s Epistemology category to dig deeper.

Many atheists—dare I say the majority—operate under the assumed premise that “there’s no evidence for God (and/or the supernatural).” Many wave this around as some sort of trump card, but I opine that such is merely biased opinion masquerading as justification for denial. Like DD, I believe “there’s no evidence for God” is one of the worst arguments floating around (a)theism, and I remain puzzled as to the strange, pseudo-intellectual pretense with which I see that argument waged. Today and tomorrow, I’d like to review two examples from science’s history that I think illustrate the weakness of the “there’s no evidence for God” argument. The larger analogy to (a)theism should be apparent.

In actuality, what the person who utters those words really means is that they’ve not been persuaded by anything hitherto offered as evidence, which is an accurate assessment of the matter. From an atheist, this is also a tautology, because if it’s known that the person who says “there’s no evidence for God” is an atheist, that they’ve not yet been persuaded by any evidence is merely redundant. In rigorous discussion, I believe one would be justified in rejecting the “no evidence for God” argument solely on these grounds (subjectivity, tautology), but I think we have other sound reasons to reject it.

Note that “there’s no evidence for X” is really just a generic argument where X always represents some proposition whose theoretical or ontological possibility is being denied. Yet, show me a true theory today that did not have its skeptics and doubters yesterday. Airplanes, telephones and relativity were all vehemently objected to by skeptics and doubters who now ironically enjoy the benefits of each. Before more optimistic minds made these things happen, many skeptics claimed they’d never happen.

This leads to an interesting question: what does it mean to say that we have evidence for a given proposition? With that in mind, let’s go ahead and take a look at asteroids.

Giraffes, X-Rays, & The Earth’s Axial Tilt: My Response To D

November 16, 2009

First, some backstory to this admittedly oddly-titled entry: Ebonmuse has a post titled Ten Questions To Ask Your Pastor in which he uses the following rhetorical device:

Why do Christians believe in the soul when neurology has found clear evidence that the sense of identity and personality can be altered by physical changes to the brain? —Ebonmuse, Ten Questions To Ask Your Pastor

My immediate questions were, “What in the Christian concept of the soul suggests that our sense of identity and personality shouldn’t be altered by physical changes to the brain?”

Response To DD’s “What Biblical Inerrancy Really Means” Pt. II

November 7, 2009

I've reread DD's arguments a few more times, and I'd like to give them more thorough address, mostly to show why I think they are not justified by a solid foundation of logic, or historical fact. As we noted yesterday, DD's first objection to Jesus' response to the Sadducees as described in Matthew 22 was that,

..Jesus tells the Sadducees that they are wrong because they do not know the Scriptures… then proceeds to “correct” them by declaring that “at the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven”—which is not written anywhere in the Old Testament Scriptures!

In that post, DD also introduced the unsupported claim that,

..the Sadducees believed in the idea that the dead continued to exist as disembodied spirits…

I'd like to stop here and see if perhaps DD's claims contain any assumed premises or historical inaccuracies. I believe they do.

Competing Models Of Consciousness

November 6, 2009

For lack of a better word, the existence of “the supernatural” is perhaps the second most foundational claim behind nearly every religion. From the monotheistic, patriarchal religions such as Judaism, Islam and Christianity, to the more esoteric Eastern mysticism, to Hinduism to today’s modern Aquarianism, the idea that existence extends beyond the physical plane is a key undercurrent. Each of these religions — and many more — claim that something akin to a supernatural realm exists. Very plainly one can see that without this “other world,” the foundational claims of many religions unravel from the core and reduce to metaphor at best. So, if I want to establish the plausibility of the MGH, establishing the plausibility of this “other world” seems a good place to start.

Response To DD’s “What Biblical Inerrancy Really Means”

November 5, 2009

So Deacon Duncan of Evangelical Realism wrote a recent post in which he attempts to justify his opinion that the Bible is not the inerrant word of God. This time, his strategy consists of objecting to Jesus' answers to the Sadducees when asked about marriage and the resurrection as recorded in Matthew 22. For those prone to reading source material, you might want to also absorb Exodus 3:6.

On Perseverance & Trolling

October 30, 2009

Well, well! A post about trolling from he who’s been labeled a troll! No, this isn’t going to be another boring argument about why I think so-and-so is mistaken in labeling me a troll. Nope, not today.

I’m still waiting on something in the mail that relates to the next post I need to write. So, today’s quick post is going to clarify that yes, I still think trolling is generally a disruptive activity that tends to obscure clear resolution of intelligent debate. However, this post will also clarify my position that – depending on the actual motives of the person labeled the troll – trolling can also be an effective strategy that can actually promote clear resolution of intelligent debate.

More Attempts At Defining Consciousness

October 28, 2009

Well, I’ve run into some unexpected difficulty getting my hands on a certain article, so the article I wanted to post yesterday is going to have to wait some more. This afternoon I’d just like to offer the following to see how people of varying worldviews react, and if anybody can add anything or make any other valuable suggestions.

A few posts back I took a stab at defining consciousness:

While I hesitate to speculate on what consciousness is, I feel fairly confident in asserting what consciousness does, or what its characteristics are: consciousness affords the abilities to feel, to know, to create, to express intent and to choose. Consciousness also affords the ability to manipulate objective matter via choice

Something elemental, like wind, can certainly manipulate objective matter, yet it presumably does so independent of any choice or consciousness. For what it’s worth, I’m currently unsure to what extent I’d claim that consciousness is analogous to soul / spirit, but I believe that regardless of the distinction, any demonstration that consciousness is anything else besides a mere product of neural transactions has [the conventional cerebro-centric view of consciousness] dead in the water.

The Strange Case Of Ingo Swann: Anomalous Mental Phenomena, I

October 26, 2009

Ingo Douglas Swan (Ingo Swann) is a Colorado-native and consciousness researcher who, along with laser experts Russell Targ and Harold ‘Hal’ Puthoff at Stanford Research Institute, pioneered the field of remote viewing (RV), an anomalous mental phenomenon where subjects appear to gain information by means outside the traditional senses.

Swann sees remote viewing as an innate human ability that can be activated and practiced like any other muscle, and not all parapsychologists or practitioners share this view. Swann claims to have had paranormal experiences since youth. In one experiment, conducted by Gertrude Schmeidler, a professor at City University in New York, Swann was apparently able to cause temperature fluctuations in sensitive equipment presumably by pure thought. Some of these thermometers were spread openly about the room, others were locked safely inside Thermos containers. The test went by sequence, in which Swann focused on a specific thermometer during each stage of the test. He was not allowed to move around the room and was given 45 seconds to rest between stages. Even amongst the sealed instruments, Swann was able to effect changes in temperature up to almost a full degree Celsius.1
